Measures
1. Check that the grid
voltage is within the
normal range.
2. Check the connection
of the AC output
power cable. If the
cable connection is
proper but the alarm
occurs frequently and
affects the power
production of the PV
plant, contact the
local power operator.
1. If the alarm occurs
accidentally, the
power grid may be
abnormal temporarily.
The SUN2000
automatically recovers
after detecting that
the power grid
becomes normal.
2. If the alarm occurs
frequently, check
whether the grid
frequency is within
the acceptable range.
If no, contact the local
power operator. If yes,
modify the power grid
